Abstract

Background: There is debate regarding nonoperative versus surgical treatment of thumb ulnar collateral ligament (UCL) tears with avulsion fractures. The aim of this study was to evaluate the fragment size in relation to the UCL footprint size in patients with an avulsion fracture injury and to find risk factors associated with surgical treatment.

Methods: In a cohort of avulsion fracture injury patients, the largest side of the fragment was divided by the average reported UCL footprint size (ff-ratio), and a logistic regression was performed to find variables associated with surgery.

Results: The mean ff-ratio was 1.1 in 114 patients with an avulsion fracture injury. Metacarpophalangeal (MCP) joint instability, rather than the largest fragment side, was a significant risk factor for surgery.

Conclusions: An avulsion fracture fragment associated with thumb UCL injury approximates the dimensions of the UCL footprint. In addition, MCP joint instability was associated with surgery in patients with avulsion fracture injuries.

拇指尺侧副韧带撕脱骨折碎片的形态学分析及手术治疗的危险因素。

背景：关于非手术还是手术治疗拇指尺侧副韧带撕裂并撕脱骨折存在争议。本研究的目的是评估撕脱性骨折损伤患者的碎片大小与UCL足迹大小的关系，并寻找与手术治疗相关的危险因素。方法：在一组撕脱性骨折损伤患者中，将碎片的最大一侧除以报告的平均UCL足迹大小（ff-ratio），并进行逻辑回归以寻找与手术相关的变量。结果：114例撕脱性骨折的平均断比为1.1。掌指关节（MCP）不稳定，而不是最大碎片侧，是手术的重要危险因素。结论：与拇指UCL损伤相关的撕脱性骨折碎片接近UCL足迹的尺寸。此外，MCP关节不稳定与撕脱骨折损伤患者的手术有关。
